Math Problem Statement
dt x->0 SINX/LOG(1+X)^(1/2)
Solution
The given expression is the limit as of :
To solve this, let's first analyze the behavior of both the numerator and the denominator as .
-
Numerator: As , \sin(x) \approx x \quad \text{(since \sin(x)x near zero)}. So, as .
-
Denominator: For small values of , we can approximate using the first term in its Taylor expansion: \log(1+x) \approx x \quad \text{(since \log(1+x) \approx xx)}. Hence,
Now the expression becomes:
As , .
Thus, the limit of the given expression as is:
